[Stoves] Fly ash cement and of levels of radioactivity?// RADON

Bamboo Science Group: Re: [Stoves] Fly ash cement and levels of levels of radioactivity?

 

As you guys delve into fly ash cement, I was curious if the levels of some of the ashes radioactive elements (Cs-137, Sr-90 and K-40) have been measured. The fly ash concentrates these natural occurring isotopes and could be problematic.

Dear G.

 

    Only K-40 is natural  !  gamma source of about 2000 Kev

Cs-137 is man made gamma from reactors or boms fall out of 660 Kev

Sr-90  / Y is man made also from reactor waste and boms but beta radiation.

 

Fly ash has Uranium  with the isotopes till lead , low in beta and little in the dangerous ALPHA if ingested or sniffed into the lungs .

Radium alpha and gamma and radon gas most alpha and changes to POWDER POLONIUM ALPHA CONTAMINANT into your LUNGS ;

2000 bq ALPHAS into your LUNGS gives CANCER after 1 year .!(Tested with 1 microgram Pu-239  +-  5,5 MeV      )

So wise guy 6bq each day sniffed into your lungs …..can give you a HIT !

Not 600 Bq / Kg meat you eat with Cs 137 .gamma .

Imagine the size  equation:  1 alpha as 1meter=1000mm canon-bullet versus Béta / gamma as a 1 mm bullet .

Schoolbooks mention ALPHA is not penetrating paper and only 30 micron in liquid ……BUT IT IS THE BIGEST RADIATION  DANGER INSITE OUR BODY .

The Brit has  right ! 

The Russion a “DURTY”  EUROPE CONTAMINATOR ! On the roof of the Chernobyl broken reactor ,workers were testing if alpha should be dangerous ….!.

Lapland rendears  40 000 Bq/Kg  and   600Bq/Kg meat is MPD  maximum permissible Dose… to sell !

     Our fly ash Uranium/Thorium/Radium/ Potasium from a coal power plant disturbed our beta counter for urine tests at 300 meter distance by wind! A 30mm Geiger with 60mm guard Geiger needed nitrogen gas flow as contra air contamination !!!

Your radiation toy DOUS NOT MEASURE ALPHAS ! unless a 30 mm thin mica 525 Philips tube .

 ---------------------------------------------------------------------------------------------------------------------------------------------------

RADON = ALPHA and dauchters Po 218   and :THORON and dauchters will be more by fly ash .

Normal RADON=40Bq /m3 =0,4 pCi/L  = 0,004 pSv /L

RISKY RADON!!! 400 Bq/m3=4pCi/L= 0,04 pSv/L    You use 1m3 air /hour

ALPHAS damage your DNA !   RADON=GAS but daughters are dust accumulating into lungs .

Don’t buy a 200$ radiation counter in uSv it measures NO ALPHAS !!! But Béta gamma .

 

For the Fukuchima  JAPANESE : measuring(I saw) drinkwater with a Geiger toy, SEE NOTHING …

But 36000 Bq/L  Cs 137 =1mCi water measures only 100 Bq with an industrial  contamination monitor because of ABSORTION in water and geometry of measuring plus efficiency of the detector assembly .

Conclusion :  do not count ALPHAS by BETA/ GAMMA !
